Application led June 23, 1922. `Serial No. 570,407.

To aZZfwLof/n 'it may concern:

citizen of the United States, residing at the city of New York, borough of Manhattan,

in the county of New York and State of New York, have invented certain new and useful Improvements in Drip Pans, of which the following is a specification.

This invention relates to sanitary appliances and has particular reference to water safes or drip pans for use in connection with the drip water from ice boxes'or refrigerators in dwelling houses, apartments, orV other analogous places.

Among the objects of the invention is to provide a drip pan having peculiar adaptability for being kept clean and sanitary as well. asto prevent any possibility' of overflow or leakage of drip water upon the floor. IlVith the foregoing and other objects in view the invention consists in the arrange ment and combination of parts hereinafter' described and claimed, and` while the invention 1s not restricted to the exact details of construction disclosed or suggested herein,

still for the purpose of illustrating a practical embodiment thereof referencey is had tothe accompanying' drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a vertical section indicating diagrammatically one adaptation of my improvement to a refrigerator. v

Fig. 2 is a plan view of a pan showing a cover, a portion of which is broken away.

Figf isa vertical section on the broken line 3-3 of Fig. 2.

Fig. 4 is a vertical'transverse sectional detail on the line 11-l of Fig. 3, showing espe cially the flush inlet and its relation to the discharge outlet from the pan.

Figs. 5 and 6 are sectional details of modilied forms ofcouplings or unions which may be employed between the pan `and the stand or waste pipeextending downward through the building. v f

Referring now `more specifically to the drawings, the waste pipe 1() is extended downwardthrough the floor l1l and along a wall 12 adjacent to which is located a refrigerator'l?) having a drip pipe 14.

The pan comprises or includes a flat dish like-body 15 whose bottom 16 is inclined rearward toward the discharge outlet 17 the axis of which is substantially horizon- Beit known that I, JoiiN J. I'IIGKEY, a

tal' and through the deeper side of thepan. The pan is `bounded by an upwardly projecting-'flange 18 of any suitable design or finish and adapted to have expanse enough to receive the drip from any ordinary `ice boX vor refrigerator if the pan is left with its top open. Y

- The discharge youtlet 17 comprises a nipple 'preferably threaded internally with a left hand thread 17 for the attachment of a coupling having right and left threaded ends for use in" places where the pan is attached too close to the lloor for it to be turned. 'Ihe nipple is provided also with an external thread 17 for an outside union such as suggested in Fig. 1 or as in Iligs. 5 and G.

Any suitable guard means may be formed over or provided for the discharge outlet 17. For this purpose I indicatea sort kof grill lincluding vertical bars 19 and a trans verse bar 20 forming vertical slots 21and an overflow slot 22 at the top. y f As indicated I may provide for the pan a closure or lid 23 approximately of disk form` and having a threaded periphery cooperating with an internal thread 24E formed on the rim 18, the lid being turned into or out of place by the application of a tool Vto the central boss 25 of angular form. This lid is imperforate or sdlid except for a threaded boss 26 into which the drip pipe 1e maybe tapped and also it is provided with one orl more tapped bosses 27 into which I sometimes connect hot and cold water pipes from the house for flushing purposes. These flush openings are shown however plugged at 28 because I prefer to employ a flushinlet such as shown at 29 formed approxi-V mately tangentially of the bottom of the pan and directed toward the discharge outlet orthe grill portion thereof. From time to time the sediment or any accumulation of filth within the pan may bedislodged and discharged. positively by introducing a jet of water through the flush port 2S)- from any water pipe in the building, the flushing water dashing directly against the grill and because of the tangential arrangement will swirl around the entire inner surface of the pan, thereby serving to thoroughly dislodge and cleanse the interior of the pan whence the material will all be discharged ntO th@ waste pipe .10,

The back of the pan may be provided Vwith one or more ears 3.0 through which a screw may be passed into theivall to additionally strengthen or stiften the connection VVbetween it and the other parts.

In some instances, as in the case of unusually large pans, it isadvisable toprovide" a support for the front portion of the pan,

although in the usual practice the entirer be Aborne by thev Weight of the pan may nipple 17. To this end I shoW a leg 3l threaded for vertical adjustment inv a boss 32 formed or'cast on the bottom of the pan.V

The herein describedfdish like drip panV for refrigerators having an kinlet for drip Water and a discharge outlet extending laterally from one side and adjacent to the bottom of the pan, grill means Within thev pan guardingsaid lateral outlet, and means separa-te from the inlet and directed horizontally and tangentially'across the inside bottom portion of the 'pan directly against the grill for admitting aV flushing fluid for dislodging accumulations of sediment from the grill.

In a drip pan for refrigerators, a' main body of substantially circular form in plan and having a lateral discharge outlet at its bottom, asubstantially Water tight lid removablysecured to the body, said lidl being provided With meansfor attaching a vertical drip pipe from the'refrigeratorthereto, and means to admit a flushing fluid across'the inside of the bottom ofthe pan independent o f the drip connection.
